Criminal justice client rehabs are available as a far better option than prison time or heavy fines for individuals who have been convicted of any type of alcohol or drug related crime. For example, a person who has been in prison for driving while impaired of drugs or alcohol may be eligible to get rehab services because of their problem instead of serving time in jail. The judge might order the individual receive rehabilitation, either alone or together with other sentencing. First-time offenders in particular are often given the opportunity choose a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it is a possibility. The concept behind criminal justice client rehabs is that it is far more effective and efficient to invest commitment into rehabilitation than punishment. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients that do take part in rehab have a much better probability of remaining out of the judicial system following rehabilitation.
